Q: My PCMCIA card doesn't fit into the socket. It looks like there's a key on the side that prevents it from going in all the way.
PCMCIA cards can be run at different voltages. ADS products currently support 5 and 3.3V PCMCIA cards. The socket is keyed to support cards that can operate at up to 5V. Your card is likely a 3.3V-only card.
